accelerated itbs in smoking cessation

Conditions: Nicotine Dependence; Smoking Cessation

Summary: cigarette smoking is one of the foremost causes of preventable disease and premature death. in 2014, 68% of adult smokers wanted to quit smoking and in 2017, 55.1% of adult smokers had made a quit attempt. however, only a small percentage of adult smokers (7,4%) achieved to quit smoking. transcranial magnetic stimulation (tms) is a novel, powerful, non-invasive brain stimulation therapy. this study used theta burst stimulation (tbs), a newer form of rtms protocol that can be delivered in a shorter duration compared to the standard rtms protocol, while delivering a comparable number of pulses. it is a tolerable, powerful, and useful tool in non-invasive brain stimulation therapies. this double-blind randomized control trial evaluated the efficacy of 4 itbs sessions per day during 5 consecutive days over the left dlpfc in smoking cessation. moreover, it investigated whether the exposure to smoking-related cues during the rtms treatment, compared to neutral cues impact cigarette craving.

cigarette smoking is one of the foremost causes of preventable disease and premature death. in 2014, 68% of adult smokers wanted to quit smoking and in 2017, 55.1% of adult smokers had made a quit attempt. however, only a small percentage of adult smokers (7,4%) achieved to quit smoking. behavioral and psychological interventions, pharmacological interventions as well as nicotine replacement therapy are some of the most used interventions for smoking cessation with medium to low success rates. nonetheless, in recent years there has been growing interest in new, alternative, and effective treatments for smoking cessation. transcranial magnetic stimulation (tms) is a novel, powerful, non-invasive brain stimulation therapy. tms non-invasively (transcranially) delivers magnetic pulses to a brain region, inducing electric a current that can depolarize neurons and induce action potentials. this study used theta burst stimulation (tbs), a newer form of rtms protocol that can be delivered in a shorter duration compared to the standard rtms protocol, while delivering a comparable number of pulses. it is a tolerable, powerful, and useful tool in non-invasive brain stimulation therapies. this double-blind randomized control trial evaluated the efficacy of 4 itbs sessions per day during 5 consecutive days over the left dlpfc in smoking cessation. moreover, it investigated whether the exposure to smoking-related cues during the rtms treatment, compared to neutral cues impact cigarette craving. the investigators hypothesized that twenty sessions of accelerated theta burst simulation over the left dlpfc while exposed to smoking-related cues, would reduce cigarette consumption and cigarette cravings, accompanied by reduced stress and motivation to quit smoking, compared to both active and sham stimulation with neutral-cues. a total of 104 cigarettes smokers, who wanted to quit smoking, were enrolled and were randomly divided into the three experimental groups: the first group received active aitbs stimulation while watching neutral videos, the second group received active aitbs stimulation while watching smoking-related videos and the last group received sham stimulation while watching smoking-related videos. primary and secondary measurements were performed at the baseline, during the treatment period, at one week, one month and six months post rtms treatment.
